SSM1002MA
High Voltage 3-Phase Motor Driver
Features and Benefits
▪
Each half-bridge circuit consists of a pre-driver circuit that
is completely independent from the others
▪
Protection against simultaneous high- and low-side turning on
▪
Bootstrap diodes with series resistors for suppressing
inrush current are incorporated
▪
CMOS compatible input (3.3 to 5 V)
▪
Designed to minimize simultaneous current through both
high- and low-side IGBTs by optimizing gate drive resistors
▪
UVLO protection with auto restart
▪
Overcurrent protection with off-time period adjustable by
an external capacitor
▪
Fault (FO indicator) signal output at
protection activation: UVLO (low
side only), OCP, and STP
▪
Proprietary power DIP
package
Description
The SSM1002MA inverter power module (IPM) device
provides a robust, highly-integrated solution for optimally
controlling 3-phase motor power inverter systems and variable
speed control systems used in energy-conserving designs to
drive motors of residential and commercial appliances. These
ICs take 85 to 253 VAC input voltage, and 25 A (continuous)
output current. They can withstand voltages of up to 600 V
(IGBT breakdown voltage).
The SSM1000M series employs a new proprietary DIP package.
The IC itself consists of all of the necessary power elements
(six IGBTs), pre-driver ICs (four), and flyback diodes (six),
needed to configure the main circuit of an inverter, as well as
a shunt resistor. This enables the main circuit of the inverter to
be configured with fewer external components than traditional
designs.
Applications include residential white goods (home
applications) and commercial appliance motor control:
• Air conditioner compressor
• Washing machine main drum
